' this specification.

My invention relates to machines for forming and preparing blanks,whereby they are adapted for making tubular wrappers and mouthpieces forcigarettes, which are preferably of conical or tapered shape, andalthough the machine, as hereinafter described, and

shown in the drawings, does not form the blanks into complete tubes itwill for the sake of brevity be called a cigarette-tube machine.

The object of my invention is to provide improved means for cutting theblanks from rolls or sheets of paper and for applying paste to thempreparatory to their further treatment. The nature of my improveddevices will be best understood as described in connection with thedrawings, in which they are illustrated, and in which- Figure l is aside elevation of a machine embodying my improved devices. Fig. 2 is aplan View of the machine; Fig. 3, a front elevation of the parts of themechanism shown in Fig. 4; Fig. 4, a side elevation of the ma chine,showing those parts which are cut away in Fig. 1. Figs. 5, 6, and 7 areviews of the feed-rolls and cutting-dies, illustrating the operation ofthe dies in severing the blank. Fig. 8 is a plan view of the female dieand the guard-plate immediately above it, Fig. 9 being an edge View ofthe same devices. Fig. 10 is a plan view of the carrier; Figs. 11 and12, views illustrating the action of the nippers used for carrying theblanks into contact with the paste-roll. Fig. 13 is a plan view of apiece of paper from which the blanks have been out; Fig. 14, a view ofone of the blanks, and Fig. 15 a view of the cigarette-- tube rolledfrom the blank.

A indicates the framing of the machine, upon which the movable partsherinafter described are supported.

B is the table, which supports the paper before it reaches thefeed-rolls, B indicating that part of the table which extends to thedelivery side of the feed-rolls and in which the female die to behereinafter described is formed or attached.

0 is the driving-shaft of the machine, D and D being fast and loosepulleys.

E is a gear-wheelsecured on shaft 0, and E a gear meshing with gear Eand secured on the counter-shaft F. G is a cam secured 011 and turningwith shaft F; H, a rodwhich, as shown, rests at one end on the shaft Fby means of yoke H, while at its other end it is attached at I to alever I, journaled on shaft J.

H is a cam-roller secured on rod H and resting on cam G, which gives toit and the rod H a reciprocating motion, which is imparted, of course,to the rock-lever I.

1 is a pawl having a weighted end 2', which keeps its active end 'i incontact with a ratchetwheel K, which ratchet-wheel is secured to theshaft J.

L is a star-cam having a series of &c., and preferably one point Z ofgreater length than the others. This cam is secured to the shaft J andreceives an intermittent movement of rotation through the action of thepawl I on ratchet-wheel K, the movement of rotation being equal in eachcase to the length of a cam-section Z and the cam-wheel L remainingstationary, while the pawl I is moved back to take a fresh hold on theratchetwheel K.

M is a rod conveniently supported, as shown at M, on shaft J on one endand at its other end attached to one arm of a bell-crank lever N, whichis journaled on shaft N. A camroller M is secured to the rod or slide Mand rests in contact with the cam-wheel L, the action of which is togive the rod M an intermittent reciprocating motion and through it tocommunicate an intermittent oscillating or rocking motion to thebell-crank lever N, which carries on one arm a pawl N said pawl restingon and actuating a ratchet-wheel N secured to shaft N, which is thusgiven an intermittent rotary movement. To shaft N is also secured agear-wheel N which is in gear with the wheel 0, secured to shaft 0 uponwhich is also secured the upper feedpoints 11,

roll 0'. The wheel 0 is in engagement with a similar wheel 0 on shaft 0upon which shaft is secured the lower feed-roll 0 The shaft 0 as shown,is supported and its roller 0 held against roll 0 by a lever O, pivotedat O and attached, as shown, to a spring 0 It will readily be seen thatby the mechanism described the feed-rolls O" and O are given anintermittent rotative movement and that by the action of the cam Z amovement of greater length is given to them at regular intervals. Thepurpose of this, I will here explain, is so that when the machine is fedwith strips of paper instead of by a continuous roll the action of thecam-finger Z, which should be first to come into operation, will carrythe paper through a greater distance than the action of the fingers Z,which necessarily come into operation afterward. In this way the frontedge of the strip is fed to the required distance over the rear edge ofthe female die, and the subsequent shorter movements of the strip arejust sufficient to feed an uncut portion of the sheet over the die, andthe blanks are thus cut with the greatest possible economy.

The number of the canrfingers and the arrangement of the parts actuatedby them are such that a single rotation of the cam-wheel L willcorrespond with the passage of a single sheet of paper through themachine.

I is a female die formed in or secured to the part B of thesupportingtable. The form of the die is that desired for the blank, andI prefer that the corners should be rounded, as shown, and above thetable B is secured a plate P, between which and the die P the paper isfed from the rolls 0 0 The plate P is cut away above the opening in thefemale die in corresponding shape, so as to give passage to the male dieP, which is secured to a slide P said slide being attached at its upperend to a lever P secured on shaft P to the other end of which isattached the connecting-rod P, which, as shown, is held in position atits lower end by a yoke P passing over the shaft F, and has attached toit a cam-roller P which rests upon a cam-surface Q, said cam beingattached to and moving with the shaft F and the formation of the cambeing such as to lift the rod P and force the male die down during theperiod when the feed-rolls O" O are out of operation, raising it againabove the plate I or the lower surface thereof before the motion of thefeed-rolls is resumed. The downward motion of the male die causes it topass into the female die, severing the blank from the sheet or roll ofpaper and forcing it down into or through the female die and onto areceiver or carrier situated below the female die. I prefer, however, tolimit the downward motion of the male die, so that its lower edge willpass but a short distance below the upper edge of the female die, and tocarry the blank through the female die and onto the receiver I employ astripper R, which fits into a cavity of the male die and is attached toa slide R, connected at its upper end with a lever R pivoted on shaft Rthe other end of the lever R being connected with a rod R which, likethe rod P, is steadied by means of a yoke at its lower end passingaround shaft F and is provided with a cam-roller R, which rests on acam-surface Q, attached to shaft F and rotating with it, the shape ofthe cam Q being such as to give a motion to the stripper-armcorresponding to the motion of the male die, but prolonging its downwardmotion, so that after the male die has operated the stripper willcontinue to move down, pushing the blank through the female die and ontothe receiver. This action of the dies and strippers is clearly indicatedin Figs. 5, 6, and 7 of the drawings.

The blank having been carried through and freed from the female die isnow to be transported to the pasting devices, which apply p'aste to oneof its edges. The receiver, therefore, should be a movable one, and sucha receiver I have indicated at S, the receiver having a cavity, asshown, (see Fig. 10,) corresponding to the outline of the blank. Asshown, and for use with the nippers to be hereinafter described, thereceiver or carrier has a slot 8 formed through its bottom along theside on which the edge to be pasted rests. It is attached to a slide S,supported in proper bearings on the frame of the machine and havin g acam-roller which fits into a cam-groove in a cam-roll S the cam-groovebeing of the general outline shown in Fig. 2 and having two straightsections S and S at its two extreme positions, so that the carrier Swill remain stationary for a time beneath the female die and for anothertime at the extreme point to which it is moved by the action of the camS. This cam, it will be noticed, is secured to the shaft C and isconstantly rotating with it. By the action of the cam the carrier S ismoved from beneath the female die to the posit-ion indicated in Figs. 11and 12, in which position a presser-foot or nipper U extends above itwith its edge a over the slot .5'. (This nipper U is attached to a slideU, and is freeto move up from the position shown in Fig. 11 to thatshown in Fig. 12, where shoulders U come in contact with the lower edgeU of the slide-guide, arresting further upward motion.) This position ofthe carrier S also brings it above a nipper V, which registers with theslot 3 and is supported upon a shoulder \V of a slide TV through themedium of a spring V which intervenes between the lower end V of nipperV and the shoulder \V. The slide \V has attached to it a plate or fingerV which lies alongside of the nipper V, as shown in Fig. 11.

To the slide is attached a cam-rollerW, which rests against a cam Y, theroller being held in contact with the cam-surface by the action of aspring W and the cam having a depression y, which permits the spring totion on the cam-roller.

draw the slideW up when it comes into opera- This cam, it will benoticed, is secured to and rotates with the shaft 0. When the slide Wmoves up, it carries with it the nipper V, which, moving through theslot 3, presses the blank against the nipper U and continuingto moveupward carries the blank and the nipper U upward to the position shownin Fig. 12, where further upward motion in the nippers is arrested bythe shoulders U The slideWcontinues to move upward, the spring Vyielding, and the plate l/V moves past the edge of nipper V, pushing theextreme edge of the blank against the paste-roller T and thus preparingit for the further operation of making it into a tube, as indicated inFig. 15. The action of the nippers V U is timed to take place during therest of the carrier before it moves back to its position beneath thefemale die, and this backward motion may begin at any time after thenippers have seized the blank, the nippers returning, of course, totheir original position before the carrier returns with a new blank.

I have not shown in the drawings any mechanism for removing the blankafter its edge has been pasted or for carrying on the further operationsnecessary in forming or filling the tube, my present invention having noreference to such mechanism, but simply going so far as the formation ofthe blank and the application of paste to it.

It only remains to note the mechanism by which the paste-roll isoperated.

' T is a paste-box having in it paste-rolls T and T the roll T having apart of its surface exposed and lying immediately above the edge of thenipper U. The paste-rolls are geared together and given an intermittentmotion of rotation by means of a pawl t acting on a ratchet secured tothe shaft of roller T, said pawl being secured on the end of arock-lever i actuated through a connecting-rod t by a lever-arm securedto the shaft P This shaft is a rock-shaft receiving its motion from thelever P, which is attached to it and which is actuated,as beforedescribed, by the cam Q and operates in turn the male die. By thisarrangement it will be noted the motion of the feed-rolls correspondswith the motion of the male die, so that the pasterolls are stationaryduring the time when the carrier lies beneath them and while the nippersare lifting the blank to its surface.

It is of course apparent that the specific arrangement of cams,connecting rods, &c., illustrated in my drawings could be very greatlyVaried without departure from my invention, and except where the saidspecific mechanism is especially referred to in the claims I do not wishto be understood as limiting my invention upon its use.

It is also apparent that the machine herein described, and shown in thedrawings, can

.be used for forming and preparing blanks of paper or similar materialand adapting them for tubes which may be used for other purposes thancigarette wrappers or mouthpieces, and I do not wish to limit myinvention to tubes of any special shape or for any special use.
